DTC P0AE6-225: Hybrid Battery Precharge Contactor Control Circuit Low [11/2016 - ]: Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
The SMRs (System Main Relays) are the relays that connect or disconnect the high voltage power system in accordance with commands from the hybrid vehicle control ECU assembly.
There are 3 SMRs and 1 system main resistor. SMRB, SMRP, SMRG, and the system main resistor are located in the hybrid battery junction block assembly in the HV battery.
To connect to the high voltage power system, the vehicle will first turn on SMRP and SMRB to charge the vehicle through the system main resistor. Then, SMRP will be turned off after SMRG is turned on. To shut off the high voltage power system, SMRB and SMRG are turned off.
